Abstract (en)

The present invention pertains to a polymer composition comprising one of poly-D-lactide and poly-L-lactide bonded to an anionic clay mineral and the other of poly-D-lactide and poly-L-lactide not bonded to the anionic clay mineral. In a preferred embodiment, the anionic clay mineral is a hydrotalcite or a meixnerite. The polylactide composition according to the invention combines a high polymerisation rate with a low amount of contaminants in the system.
